Product Overview

Gyprock Hardwall Plaster is usually applied over cement render or concrete to provide a smooth finish for painting or decoration.

It is a low VOC plaster manufactured by Gyprock in Australia to stringent product specifications and packed in an orange coloured bag. 

Typical Applications

Hardwall Plaster is typically used in both residential and commercial construction as a finishing coat over cement render or concrete in preparation for painting. When used with hydrated lime (lime putty), a high gloss finish is produced which can be waxed to create a decorative finish. In hot or dry conditions it may be necessary to wet the surface before application to prevent the plaster drying out before setting.
